I use default buddypress theme and gallery creation is from buddypress through gallery plugin. Not only… in bbpress forum is the same problem: user with Samsung galxy s3 Don’t see button “create” or “submit”

I resolved,
for those who have the same need to modify files in / yoursitename.com / wp-content / plugins / BuddyPress / bp-activity / bp-activity-template.php
on lines 144 and 347 replace ‘per_page’ => 20 with the number you want eg ‘per_page’ => 50
